Hydration and Heat Development

  • Chapter
  • First Online:
Thermal Cracking of Massive Concrete Structures

Part of the book series: RILEM State-of-the-Art Reports ((RILEM State Art Reports,volume 27))

Abstract

The driving process of early-age cracking in massive element is the hydration and reactions of the binder that composes the concrete. Indeed, these reactions are highly exothermic and lead to heat generation in the structure. It is thus of primary importance to be able to characterise and predict the heat generation of binders in order to assess the early-age cracking risk of a concrete structure. The first section of this chapter presents the main physical phenomena responsible for this heat generation. It must be kept in mind that only the general phenomena of hydration are presented. The aim is only to present how the chemical reactions lead to heat development and water consumption (which are of interest for our purpose). The reactivity of binder is a large scientific subject, and more detailed review can be found on this subject in other RILEM TCs (for instance, 238-SCM). The second (and main) section of the chapter is dedicated to the modelling of the heat development induced by cement hydration. Several approaches are presented: affinity-based models (that can be easily implemented in finite element codes), microstructural models (even if they are less adapted to the massive structure modelling), data mining, or inverse analysis.
